Abstract
A novel eutectic solvent (NES) includes one or more derivative(s) of methanesulfonic, one or more ammonium salt(s) and one or more hydrogen bond donor(s). The disclosed NES may exhibit qualities such as low freezing and eutectic points, low viscosity, negligible vapor pressure, non-volatility, less water content, high potential window, high thermal stability, high solubility, long shelf life, high recyclability, high biodegradability, high ionic character, air and moisture stability, non-corrosive, non-mutagenic, economical, non-flammable, etc., hence having broader applications.
Claims5
A eutectic solvent comprising:
- one or more derivative(s) of methanesulfonic acid selected from its salts with metal ions selected from the group consisting of manganese, zinc, cerium, nickel, titanium, copper, sodium, potassium, and calcium;
- one or more ammonium salt(s) having general formula NH4X, where X is selected from the group consisting of chloride, methanesulfonate, acetate, sulphate, triflate, and trimethanesulfonate;
- and
- one or more hydrogen bond donor(s) selected from the group consisting of urea, thiourea, glycerol, oxalic acid, acetic acid, ethylene glycol, acetamide, benzamide, adipic acid, benzoic acid, and citric acid,
- wherein the molar ratio of derivative(s) of methanesulfonic acid, ammonium salt(s) and hydrogen bond donor(s) is in the range 0.5-3:2-7:8-13, respectively.
